Abstract
This invention relates to non-aqueous formulations comprising resins and/or polymers with a higher solids content and a solvent which is a diether of the general formula: R.O.R..sup.1.O.R.sup.2, wherein each of R, R.sup.1 and R.sup.2 is a straight or branched chain, saturated aliphatic hydrocarbyl group having from 1 to 5 carbon atoms and in which R and R.sup.2 are the same or different alkyl groups and wherein R.sup.1 is an alkylene group, said formulation containing less than 25% w/w of solvents or diluents having free hydroxyl groups. The formulations are particularly useful in vehicle refinishes.
